DYNDyne Therapeutics, Inc.
Is it safe?
Caution warranted: heavy debt (BB) and big price swings.
Insiders were net sellers (-$72.3M, 90 days to Oct 22, 2026), selling is often routine.
Net cash, but unprofitable, speculative. A rule of thumb on leverage, not a credit rating.
Large price swings, high volatility. Worst drawdown -86% · now 42% below its 52-week high.
Against the whole market›
Percentile against every name Ryufin tracks. Higher is better; the tick marks the middle of the market. Context, not one of the checks above.
Where this answer is blind. Altman sits structurally low for utilities and pipelines; Beneish runs high for fast growers, since sales growth alone lifts it; banks and REITs are excluded.
